方法一：system函数
| 1 |
ip add | grep enp0s8 | grep inet | awk '{print $2}' | awk -F"/" '{printf $1" "}{cmd="hostname";system(cmd)}
|
| 1 |
[root@rac1 ~]# ls | awk '{printf $NF" "}{cmd="hostname";system(cmd)}
|
方法二：使用变量（获取变量的时候已经执行命令）
ls |awk '{print i$0}' i= `pwd`'/'
或
[root@rac1 ~]# ls -a |awk '{print i$0}' i= "`pwd`/" 注意：这里的双引号不可以用单引号替换，单引号内强制为字符串-不执行引号内的命令。
[root@rac1 ~]# ls -a |awk -v i="`pwd`/" '{print i$0}'
方法三：把命令传递给bash
| 1 2 |
[root@rac1 ~]# awk 'BEGIN{print "echo cange"|"bash"}'
cang
|
| 1 2 3 4 5 6 7 |
[root@rac1 ~]# ls -lh | awk '{print "echo cange"|"bash"}'
cange
cange
cange
cange
cange
cang
|
方法三的内容延伸：执行多重命令
| 1 2 3 4 5 6 7 |
[root@rac1 ~]# ls -lh | awk '{print "echo cange `date +%Y-%m-%d`"}' | bash
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-1
|
| 1 2 3 4 5 6 7 8 9 |
[root@rac1 ~]# ls -lh | awk '{print "echo cange $(date +%Y-%m-%d)"}'| bash
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
cange 2021-08-11
|
结合输出引号和shell命令：
| 1 2 3 4 5 6 7 8 9 10 11 |
[grid@rac1 ~]$ find $ORACLE_BASE/diag/crs/`hostname`/crs/trace/ -ctime -1 | awk '{print "echo "$0" ` stat -c""\"" "%X %Y %Z" "\""" "$0"`"}' | head -n 10 | bash
